Reading/writing in the terminal

[JMLX42]

Hello,

I need to be able to:

1. write a string/a vector of chars to the terminal
2. read the terminal

For 2., here is what I came up with:

fn read_terminal(&self) -> String {
        self.terminal_backend
            .last_content()
            .grid
            .iter_from(Point::new(Line(0), Column(0)))
            .map(|cell| cell.c)
            .collect::<String>()
    }

For 1., I think using TerminalBackend::process_command() is the right option, but BackendCommand is not exposed by lib.rs so this method cannot be called.

Hi! Thanks for interesting of my project. I've plan to convert this crate and my another my crate (iced_term) to one crate that providing all you need to create terminal emulator, but right now:

• For 1 - I can create the method that provide current terminal emulator content. It will be fit for you?
• For 2 - I can just accept your PR

write a string/a vector of chars to the terminal

I have implemented my own "fake" Pty instead. And I give that Pty to the TerminalBackend. I'll finish, clean up and provide a PR.
